Your solenoids inside the transmission may be bad, try to unplug the 4 wire connector to the front of the transmission to see if the problem still continues, if it doesn't then its the solenoids causing the problem, they stay engaged into gear thus car dies and when you put on park, it starts fine again, when you shift it dies again. I had the same problem, changed the all solenoids fix my problem. Hope it helps.

it sounds like you have blown fuse to the Alternator.. I don't know what car you are talking about but they charging systems vary.. But if alternator isn't getting all the power it needs it won't charge. this should be checked.

good luck

Check mega fuse. Side of fuse box under hood. Slide cover off and test both studs. Should have 12 volts on both studs. If not. Fuse blow.

You are on the right track by finding the injector pulse missing.
The computer grounds the injectors based on signals from the cam and crank sensors. You may have to use a scanner to check for trouble codes in the computer and watch the sensors work.
The problem could also be a relay or the key switch.

check fuel pressure at the manifold (regulator and fuel pump/ filter)
